Add support for the video controller IP block included into Xilinx ML300
and ML403 reference designs.

-----
The driver has been tested with Xilinx ML300 and ML403 reference designs.
The two first version has been posted to linuxppc-embedded, and this
version tries to address all the comments and criticism received.
The platform device registration for Xilinx ML300 and ML403
moved into separate patch (will be posted to linuxppc-embedded
in couple minutes).
Here is the platform device registration part.
Thanks,
Andrei
